APPENDIX E

Linear Slide Option

Features

Screw driven slide offering exceptional linear speed, accurate positioning and long life at a compelling value

High bidirectional repeatability of up to 50 micro-inches (1.25 microns)

Positional lead accuracy of 0.0006"/in. – accuracies to 0.0001"/in. available

Linear speeds not limited by critical screw speed

Standard leads:

-

0.10" travel per revolution

- 0.50" travel per revolution

-

0.20" travel per revolution

- 1.00" travel per revolution

Achieve speeds that exceed 60.0"/second while offering excellent repeatability, accuracy and axial stiffness

Optional sensor flag kit available for home, limits and general purpose inputs

Assembly includes a precision aluminum guide and carriage which is driven by a precision rolled stainless steel lead screw

Sliding contact areas coated with TFE (Teflon) permanent lubrication to offer a low 0.09 coefficient of friction

Exceptional torsional stiffness and stability

Standard lengths from 12.0" to 42.0", longer sizes available upon request

Comes standard with wear-compensating, anti-backlash driven carriage

Additional passive carriages or slides available to support cantilevered loads

Easily mountable with provided mounting flange and holes

Extrusions provided for sensor mounts

Figure E.1: Speed Force Limitations

Speed/Force correlating equations:

1Axial Force = Ffriction + Facceleration + Fgravity

Ffriction = (Weight)(0.09)

Facceleration = (Weight)(Acceleration) / Accel. of gravity

Fgravity = 0 for horizontal application and 1 Weight for vertical application

2(Axial Force)(Screw Lead) Torque = (0.393)(Screw Efficiency)

Force in lbs; Torque in oz-in, Lead in inches/rev
